SPECIFICATION forming part of Letters Patent No. 314,070, dated March17, 1885.

Application filed December 2, 1884. (Model) To aZZ whom it may concern:

Beitknow n that I, MATHIEU SoUvIELLE, of Paris, France, residingtemporarily at Washington, in the District of Columbia, have inventednew and useful Improvements in Telescopic Respirators, of which thefollowing is a specification.

This invention relates to that class of portable or pocket respiratorswhich are made to receive various medicaments held in absorption by asuitable packing or filling and de signed to be vaporized or atomized byair drawn into the lungs through the month while in the act ofbreathing. i

The object of the invention is to provide a respirator which is simplein construction, effective in operation, and can be adjusted to receivedifferent amounts of absorbent or medicated packing, and when, not inuse can be placed in such position as to take up comparatively littlespace and firmly and safely hold the medicated packing in positionwithin the respirator.

The invention consists in a respirator consisting of two sections orshells, one of which is open at its outer end, and is provided withcurved edges, so as to fit closely around the mouth of the patient, andis provided at its other end with a foraminous or perforated head, andat some point between its ends with a circumferential bead or rib forstrengthening said section and limiting the distance it can be enteredinto the other section. This inouth-piece portion of the respirator fitstelescopically into the other section or shell, that is also providedwith a perforated or foraminous end head, between which and the similarhead of the mouth-piece section there is placed and retained anabsorbent and medicated packing'or filling of sponge, cotton, preparedtar, or other suitable material. The mouth-piece section can be moved inand out of the other section, so as to increase or diminish the size ofthe chamber containing the absorbent or medicated packing, wherebyprovision is made for tightly or safely holding such material in varyingquantities, according to the requirements of the case. XV hen therespirator is not in use, the mouthpiece section is withdrawn from theother section and placed into the latter in an inverted position, so asto decrease the compass of the device for convenience in storage andtransportation.

In the drawings, Figure l is a perspective view of a respirator inposition for use. Fig. 2 is a perspective View representing thecomponent sections or shells of the device in a separated state. thedevice with the absorbent or medicated packing held between twoforaminous end heads ofthe component sections or shells. Fig. 4represents the respirator inverted and packed in a box, with a bottle ofmedicated fluid designed to accompany the respirator.

The reference-numeral l designates one of the shell shaped sections ofthe respirator, which has its outer edge out on a curved line, or ishollowed out, as is shown at 2, so as to fit closely around the mouth ofthe patient or user. The other section, 3, of the respirator is alsomade in the shape of the shell, and is designed to have the section 1fitted into the same in either of the positions represented by Figs. 1and 4. Both component parts of the respirator are preferably of anelliptical or oval shape in cross-section, and may be made of sheetmetal, glass, celluloid, india-rnbber, or other appropriate material notliable to be affected by the medicaments used in the same. Themouthsection of the respirator is formed with a circumferential bead orrib, 4, which serves to impart strength and rigidity to such section,and also limits or defines the distance said section can be entered intothe other section, 2. The outer ends of both sections comprising therespirator are each provided with a foraminous or perforated end head,5, which, when the parts are in the position shown in Fig. 3, formbetween them a chamber or space that is designed to receive a packing orfilling of some absorbent or medicated material. I have in said figuresshown said chamber when filled with several coiled strips of preparedtar and a superposed absorbent or porous packing that may be medicatedby pouring on it a mixture of carbolic acid, tincture of iodine,alcohol, and water, or any other medicament or fluid the vapors of whichare to be administered by passing air through the device. Thus, whendecomposition of living tissues or blood-poisoning is to be arrested,carbolate of iodine is one of the essential ingredients or active agentsFig. 3 is a sectional view of p that can be used in the instrument bysaturating or impregnating the packing placed therein. As shown in Fig.3, the mouth-section of the device is moved sufliciently far into theother section to firmly retain the absorbent packing or medicatedfilling between the two foraminous end heads. hen alarger amount ofmaterial is to be placed in the device, the two sections can be drawnapart in the manner of a telescope, so as to increase the size of thechamber that contains the filling.

For the purpose of properly separating different layers of packing orfilling, I sometimes propose to use detachable perforated plates orforaminous diaphragms, as is shown by the dotted line 9 in Fig. 3. I mayalso attach rings or loops 10 to one of the sections, for receivingbands that secure the device to the head of the patient.

When the respirator is notin use, the mouthsection is Withdrawn from theother section and is slipped into the same in an inverted l state, as isclearly shown in Fig. 4. The device, when in this position, takes upcomparatively little room, and the curved mouth-rim is inclosed andprotected and prevented from becoming bent or injured, as is readilyapparent.

Having thus described my invention, what I claim is The herein-describedrespirator, consisting of the mouth section or shell having a perforatedend head, a circumferential bead, and a curved rim adapted to fit themouth of the user, and a larger shell provided with a perforated endhead, and adapted to have either end of the mouth-section enteredtherein tele scopically, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

MATHIEU SOUVIELLE.
